Answer:
The correct answer is option B.
Explanation:
MHC or The major histocompatibility complex is a series of genes that have information and rise to cell surface proteins required for the adaptive immune system to recognize the pathogen or the foreign molecules, There are three classes of MHC - MHC1, MHC2, and MHC3.
MHC class II generally present only on antigen-presenting cells such as single nuclear phagocytes, dendritic cells, thymic and B cells.
Thus, the correct answer is option B.
Degradation means the wearing down of or slow lowering to a weaker position.
The two bacteria are considered to be anaerobic endospore-formers that deliver neurotoxins. Disease comes about when the endospores are brought profound into the tissues. The two neurotoxins meddle with engine control. Botulism poison, delivered by C. botulinum, ties the cytoplasmic films of engine neurons at the neurotransmitter and keeps the arrival of acetylcholine neurotransmitter and, subsequently, forestalls motioning to muscle cells. At the point when muscle cells don't get signals from engine neurons, they stay loose, bringing about a flabby loss of motion. The absence of engine control delivers a not insignificant rundown of side effects, the most genuine of which is a respiratory disappointment, on the grounds that respiratory muscles can be influenced by botulism poison.
If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.
<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>
- An organism that preys on other species in order to consume them as food is referred to as a predator.
- Prey is a term used to describe an organism that a predator kills.
- An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
- Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
- Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.
Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.

Answer:
Accurate - Yes
Precise - Yes
Explanation:
Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.
Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.
Note that, a measurement may be accurate but not precise or be precise but not accurate.
In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.
Therefore, the measurements are both precise and accurate.
